Lightning network blockchain
Change: the characteristics of blockchain disintermediation, consensus mechanism and non tampering can increase the efficiency of data flow, rece costs, monitor the real situation of assets in real time, and ensure the trust of all parties in the transaction chain on the underlying assets.
then why should I say that lightning bitcoin is a great currency experiment? We compare lightning bitcoin to a free economy with three major stakeholders: developers, miners and holders
so far, no blockchain project can effectively govern the three. Why? The reason is very simple. In an ICO project, the developers, coin holders and even miners are the same group. It's easy to understand. Why should he give the best interests to the ICO holders? This is obviously not in line with human nature. The reason why lightning bitcoin dares to do chain governance is related to the issuing mode of lightning bitcoin. LBTC's "governance on the chain" is another attempt to "decentralize", which is also very eye-catching. Dpos mechanism determines that there are 101 nodes in the network. At the same time, unlike pow, the right of choice is in the hands of the coin holder. These nodes will be elected by the vote of the coin holder. When the node does not act, the user can vote out of the network. According to last week's weekly report, LBTC's block browser has also added this function, which can view the operation of nodes in real time. It also paves the way for LBTC's "chain governance". In the LBTC system, all coin holders can vote to decide whether the project development proposal will go or stay, and all members of the organization can participate in the decision-making and operation of the organization. In addition, the 5000 standard of lockup after the election of the lightning node ensures that the node is both a mine pool and a coin holder. In this way, the relationship among miners, developers and users is well balanced, and the foundation of an autonomous organization is formed.
To be honest, I had the same problem with the subject at the beginning. When I saw the news, I was a little confused and went to search. As a result, when I searched for lightning bitcoin or lightning bitcoin, either lightning network or bitcoin came out... This name is quite poisonous
Let's get down to business. Let's draw a conclusion first. It's not a thing at allmany people have talked about what lightning network is. You can look at other people's answers to get a deeper understanding of its mechanism, or you can go to the official website with better English to see their papers directly http://lightning.network/ . Lightning bitcoin official website in Chinese, save the trouble of translation https://lbtc.io/ . The origins of the two lightning bolts are very similar. They both hope to solve the problem of bitcoin network congestion. One is to carry the protocol, and the other is to change the fork to consensus. The results of the two lightning bolts are also good. The transaction speed is greatly improved, which can be regarded as real-time. The following table directly shows the similarities and differences between the two:
as can be seen from the above, the differences between the two are relatively large, and should not be confused any more~
It has been ten years since bitcoin was born. Ten years ago, if someone had told his founder, Tsui Nakamoto, that this new decentralized currency would flourish in 2019, he might have thought his experiment was a success. Bitcoin is indeed likely to become a world currency. Even if it is not as magical as Nakamoto said, even today, 10 years later, there are still people criticizing the ideas in its white paper
Although bitcoin has become a widely used investment and speculative asset, e to its own design and huge demand, bitcoin is far away from its goal of completely decentralized free currency. But if the new solution does solve some of the existing problems, then its status quo will certainly be greatly improved< as long as the transaction cost of bitcoin blockchain is not higher than lightning network, users will not transfer assets to other public chains. If bitcoin blockchain can continue to expand the transaction processing capacity through other solutions besides lightning network in the future, it may eventually develop into the world currency originally conceived by Nakamoto strong>In February 2015, bitcoin developers Joseph PON and Thaddeus dryja proposed the concept of scalable off chain payment -- Lightning network in their paper the bitcoin lightning network: scalable off chain instant payments. We know that a very important reason why the bitcoin network is reliable is that all the bitcoin nodes keep the bitcoin account books. If someone wants to tamper with the transaction records, they need more than half of the computing power of the whole network. Without the trust machine of blockchain network, how can we ensure that both sides of the transaction will not go back and deny? How is lightning network realized
in short, the lightning network is based on the expansion of bitcoin. Due to the limitation of bitcoin block, a new channel is required. The process of small amount delivery can be realized through the channel of lightning network without bitcoin miner accounting, which can speed up the speed and rece the handling charge. But how can such lightning network prevent the centralization problem? More details this video is very detailed: six minutes to understand the lightning network
but how long can the lightning network land
the main idea of lightning network is very simple: put a large number of transactions outside the bitcoin blockchain
RSMC guarantees that the direct transaction between two people can be completed under the chain, while HTLC guarantees that the transfer between any two people can be completed through a & quot; Payment & quot; Channel. By integrating these two mechanisms, the transaction between any two people can be completed under the chain
in the whole transaction, smart contract plays an important role as an intermediary, while blockchain ensures that the final transaction result is confirmed.
I hope I can help you:

abey blockchain technology is from Ciprian pungela & amp; Co., two doctors in the Department of artificial intelligence from the Department of computer science, School of mathematics and information, Western University of timishwara, Romania; Vorel negru's own research project. Constant lightweight blockchain technology and multi-layer programming and extended blockchain solution are adopted. The scale of abey's blockchain remains unchanged, with only 50 active blocks. Abey blockchain technology is suitable for the use of e-money in e-commerce system for mass transactions, and has multi-level, scalability and security, and can be programmed
according to the official white paper, abey is suitable for the blockchain solution in e-commerce system, which uses digital currency to carry out mass transactions and can carry out multi-layer programming and expansion
specific implementation method of abey blockchain Technology:
using a multi-level and programmable blockchain method to realize digital currency (for simplicity, we call it "DC"). This method can pave the way for the implementation of various e-commerce purposes, such as loan financing, completion of refundable transactions and non refundable transactions. In the first layer of the blockchain, we can realize the inherent digital currency design, which is commonly referred to as the base layer ("FL"). The various upper layers built on this foundation can be used to describe various additional functions related to various business driven application examples (which we will briefly introce below). All of the above levels are fully programmable, and can be easily adapted for various applications
although most of today's digital goods store transaction balance in the blockchain, abey's method is more similar to Pascal coin digital currency. This method uses what we call a "vault" encryption structure“ The "vault" structure can only save the balance of all accounts in the network, instead of a complete list of all completed transactions, and can be reconstructed in the evolution history of the blockchain. Since vault allows the deletion of useless content at any time, it can significantly rece the storage cost of blockchain. In contrast, at the time of writing this article, the storage space required to download bitcoin database is 70gb (the alarm rate is still growing, and it is expected to reach 300gb in 2019), so it is not feasible to use ultrabooks or notebooks with small storage space (such as 120GB or 256gb) to carry out mining operation. On the other hand, the size of the abey blockchain will remain unchanged, with only 50 blocks (at the time of writing, there are more than 525000 blocks in the bitcoin blockchain)
vault fully supports digital currency transfer between accounts. In addition, vault can assign an owner defined name to each account instead of using hashing algorithms like today's cryptocurrency - which makes the account easier to remember and makes the name public
one of the important functions that vault can help prevent the daily expenses of blockchain from being too high (especially those related to transaction history) is that vault can save such states and rece the size of blockchain itself by creating a secure of blockchain states. Because there is no transaction history and all accounts can save their direct balance, the blockchain information has the feature of partial erasure. All the blockchain states that can be stored can be regarded as landmarks of the blockchain
secure data sharing:
through the block chain structure design, for each transaction sent to the network, the block chain may contain encrypted metadata. The metadata can only be decrypted by the transaction recipient. For the transaction sent to the network, the sender's public key is included in the transaction, and the transaction receiver decrypts the metadata using the public key. Since the transaction receiver holds the private key for decryption, only the transaction receiver can implement the data decryption process. From the perspective of encryption method, although bitcoin is limited to elliptic curve cryptography, blockchain metadata can use any other encryption mechanism to complete the encryption process. This not only provides complete flexibility in security selection, but also does not have any adverse impact on the structure or function of the blockchain
scalability:
since the abey blockchain supports the creation of historical landmarks by design, it is very easy for the network itself to achieve high scalability from the point of view that the blockchain will always need to store (related to the latest existing SLS). This method completely eliminates the need to store transaction history to calculate the balance of all accounts, and can directly store all account balances, so as to ensure that the specific balance information provided by all nodes in the network meets the requirements of Byzantine consistency
proof of security and workload:
it is impossible to have two-way payment operation in abey's method (in the specified appropriate scenario, the vast majority of today's mainstream cryptocurrencies may theoretically have two-way payment operation). Each transaction means that the balance of the corresponding account is updated in a relatively simple way, and there is no special way to restore the transaction from the network pending transaction team. For the abey blockchain, since all technical / functional layers are built on vault, vault is the infrastructure of our blockchain, so vault is very important for mining operations. Our proposed blockchain model is composed of a series of blocks, each of which is generated by the nodes in the network who are willing to mine. All nodes in the network can update the account balance independently according to the transaction (part of the block), and are independent of other nodes. The mining operation will affect the first functional layer. In addition to updating the balance, each node can also update other matters that may belong to the upper functional layer in the composition of the blockchain structure. Once an update occurs, a new mining incentive block will be created. The mining reward block contains a number of new reward accounts that have been assigned to miners. The miner is the winner of the above reward according to the workload Certificate (currently there are 50 reward accounts). The way to reward is to distribute the public key of all such accounts to the reward recipient
blockchain technology layer:
abey's digital currency model contains a multi-layer structure, in which the first layer represents the realization of the digital currency itself (see Figure 7 for graphic explanation). The corresponding levels include:
tier 1 → digital currency (cryptocurrency): currency transfer, mining
tier 2 → refundable transaction and non refundable transaction: allowing the use of digital justice system to complete refundable transaction
Tier 3 → related parties and commission: allowing the automatic distribution of Commission to related parties
Tier 4 → contacting currency: by lending currency, Income based on interest
layer 5 → programmable: reserved for future realization of Turing complete programming model, so as to process blockchain data in a customized way (such as smart contract)
layer 6 → custom protocol: reserved for future use
transaction type:
abey mode allows different levels in blockchain through design, Complete a variety of transaction types. The transaction types in the second layer are as follows:
1 → fund transfer: fund transfer between accounts (1-to-1 transfer)
2 → refundable fund transfer: refundable transaction between accounts. Use escrow balance instead of regular account balance
3 → key change: change the key that can be used to process the account
4 → restore the account: recover funds from the lost and invalid account
5 → set account name: define the name of the account held by the founder
6 → sales preparation: mark the account for sale
7 → move out of the sales queue: remove the account sales mark, And the account is marked as non saleable
refundable transaction and mediator:
for the vast majority of cases, non refundable transaction is equivalent to all "pay to pay" transactions in blockchain based digital currency mode. But abey has introced the concept of refundable transactions into its digital currency model. In abey mode, the transaction marked with small flag belongs to refundable or non refundable transaction. In addition, in abey's blockchain network, each account contains two types of balance: regular and unchangeable balance (used to mark the amount that the account has received and can be paid immediately, but cannot be recovered after the payment) and escrow balance (including the transaction list marked as refundable transaction and the minutes of each transaction)
8 → payment dispute: for the corresponding transaction that has been marked as a refundable transaction, the payment dispute can be initiated only by the payer
9 → refund request: for the corresponding transaction previously marked as a refundable transaction, a refund request can be initiated, but only by the payer
10 → cancel escrow: cancel the escrow funds and return the funds to the payer immediately. It can only be initiated by the payee
11 → release trusteeship: release the trusteeship fund and add the amount to the balance of the payee's account immediately. It can only be initiated by the payer
related parties and commissions:
one of the important deficiencies in today's blockchain driven financial technology is the lack of the ability to provide rewards to related parties who sell specific procts or services. The third layer of abey blockchain can solve this problem< Lending digital currency:
lending digital currency is not only a simple and quick way to allow people to borrow legal tender, but also to ensure the security of encrypted assets. Given that today's valuable digital currencies are also used for transactions, the reason why lending digital currencies is feasible is not only that it allows borrowers to mortgage any type of cryptocurrency they save, but also that it is attractive because it is a way to retain their digital assets in a completely safe or very low-risk way. In addition, abey's model also provides built-in protection through the customer vault lending gateway (VLG), and enables the VLG to act as a buffer between the lender and the borrower
12 → borrowed funds: the borrower initiates transactions in the network, announces the intention of borrowing funds, and specifies the VLG account of the borrowed funds. The transaction is similar to depositing the balance of the regular / escrow account in the selected VLG account
13 → return of collateral: the transaction is initiated by the VLG itself. VLG will return the collateral to the borrower in accordance with the risk management policy
14 → loan repayment: the transaction is initiated by the borrower. If VLG accepts repayment of the loan in digital currency, the borrower may choose to repay the loan in digital currency. Under this condition, the digital monetary fund will be converted into VLG regular account balance<
programmable blockchain:
with its associated metadata payload, the layer of blockchain can be retained to allow the further creation of intelligent contracts between peers in the network by executing the grammar based "complete Turing basic programming language" according to the original blockchain data processing mode. For each payload, encryption or public visibility processing can be implemented, and can be performed in a dedicated virtual environment (similar to a virtual machine). This method can effectively protect data security and avoid the impact of data destruction and security vulnerabilities. The main advantage of this method is that this layer can create and enforce digital contracts without any blockchain specific programming. For Ben

super game alliance SGU ecological landing application highlights: the new SGU mall DAPP will realize game assets exchange, game props selling, player data sharing, node equity replacement, etc., and the decentralized wallet will realize digital asset management, ecological application entrance, equity management, and comprehensive service platform, so as to better integrate games into life, Make playing games as easy as playing games
as for the technical team, it is said that it is an instry leader dedicated to the blockchain game field, which has not been disclosed yet. I believe the technical team will not be poor. After all, the strength is there. The blockchain technology docking game is indeed a good innovation point, and the appreciation space is quite large, so we can start with it appropriately.
The current development stage of blockchain Technology: financial value period, credit value period and governance value period. Among them, blockchain 3.0 and 4.0 are developing rapidly. It is predicted that there will be a wave of great changes in blockchain technology
ecology makes the main chain and the side chain
ecol ecology makes the team deal with the difficulties faced by the side chain. Through data isolation and cross chain audit, the business data confidentiality and security of the side chain can be guaranteed, and the balance between data transparency and business confidentiality can be solved
and support multi side chain, main side chain communication, asset transfer, both integration and division of labor, both security and convenience. The main chain is mainly responsible for security and consensus. The side chain will provide smart contracts, token issuance, asset trading, cross chain interoperability, and the structure of the main and side chains. Through slimming and pruning technology, it can effectively prevent block swelling, garbage accumulation, and shorten synchronization time. To clear the obstacles for the implementation of high concurrency and lightning network
ecol ecol makes it possible to connect different blockchains through side chain technology, which is the key to solve the problem of slow transmission speed and low efficiency in expanding the external structure of blockchain. In short, the side chain is like a channel, connecting different blockchains together to realize the expansion of blockchain. In the long run, ecolink will graally build a high-speed value Internet belonging to the side chain in the case of developing, applying and proposing solutions
